What’s Federated Searching? (1)
• Federated Search:
“A search for information using software designed to
query multiple networked information resources
via single interface.” - Online Dictionary for Library
and Information Science
http://lu.com/odlis/odlis_f.cfm
What’s Federated Searching? (2)
• Search scope: expanded
– OPACs (local, remote), databases (abstracting, full
text), digital repositories, WWW (including “deep
Web”)
• Software: federated search engine
– Standardized protocol (Z39.50, SRW/SRU, MXG)
• Results presentation: uniform interface
– Ranking: software feature that weights records by
the degree to which they meet the query’s
requirements
– Deduping: removal of all but 1 occurrence of a
record

What’s Federated Searching? (3)
“[Database searchers] don’t go to see if another
database might have more and/or better
results…. Most give up and angrily leave….
They’ll go to Google….” – Dr. Péter Jácso
